U.S. imports of Non-Medical Apparatus Using Alpha, Beta, Gamma or Other Ionizing Radiation (HS 902229) totaled $13.0M in August 2026, imported from 21 countries.
Importers of Non-Medical Apparatus Using Alpha, Beta, Gamma or Other Ionizing Radiation paid $95K in duties in August 2026, an average duty rate of 0.73% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Non-Medical Apparatus Using Alpha, Beta, Gamma or Other Ionizing Radiation imports of $13.0M in August 2026 ran 25% below the year-to-date monthly average of $17.3M.
Last updated: August 2026 dataIonizing-radiation apparatus used outside clinical settings — most notably smoke detectors (classified under 9022294000) and a broad residual category of other non-medical radiation apparatus (9022298000) — falls here. Mexico and China are the leading US import sources for this heading, with Norway, Italy, and Germany also represented. Smoke detectors using americium-241 (an alpha emitter) are the highest-volume commodity in this heading by unit count, while the residual line covers industrial gauges, level sensors, and similar instruments.

Ionization-type smoke detectors use a small quantity of a radioactive isotope (typically americium-241) to ionize air in a detection chamber — making them apparatus based on the use of alpha radiation. This places them squarely within heading 9022 rather than among general electrical safety apparatus. The HTS specifically provides for them at the 10-digit level under 9022294000, distinguishing them from photoelectric smoke detectors classified elsewhere.
Apparatus in the residual line 9022298000 that incorporates sealed radioactive sources — such as industrial level gauges or density meters — may require an NRC or Agreement State license for the radioactive material itself, separate from any CBP entry requirements. Importers should determine whether the specific article contains licensed radioactive material and obtain the necessary authorizations before shipment arrives.
